Polygon

What is the perimeter, in units, of a regular 11-sided polygon with sides of length .36363636… units?
I don't know how to find the answer to this problem. Please use words that a 7th grader can understand. Thanks!

Re: Polygon

The perimeter is the sum of all the sides of a figure. For instance, the perimeter of a triangle is the sum of the lengths of the three sides. the perimeter of a rectangle is the sum of the length of the four sides. Can you now find the perimeter of your polygon.

First of all, it would help if you wrote the length of each side as a fraction, as they are exact.

So that means each side is of a unit in length, and since there are 11 sides, the perimeter is units.
